The invention relates to the technical field of clamping devices, particularly to an optical fiber sensor clamping device. The device comprises a clamping base, clamping plates are slidably connectedin square clamping grooves, telescopic rods are connected to the tops and bottoms of the clamping plates, springs are sleeved to the surfaces of the telescopic rods, a negative pressure groove is disposed on the side face of a second circular through hole, a thick rubber block is fixedly connected to the bottom of the negative pressure groove, negative pressure holes are evenly distributed in thethick rubber block, cylindrical air suction cylinders are arranged right above vent holes, pistons are slidably connected in the cylindrical air suction cylinders, and threaded rods are rotatably connected to the tops of the pistons. The optical fiber sensor clamping device provided by the invention can realize clamping of an optical fiber sensor probe, also can fix the optical fiber sensor probeon to-be-measured skin, and does not cause measurement errors brought about by displacement deviation.
Description
technical field [0001] The invention relates to the technical field of clamping devices, in particular to a clamping device for an optical fiber sensor. Background technique [0002] Optical fiber sensor is composed of light source, incident optical fiber, outgoing optical fiber, optical modulator, optical detector and demodulator. Optical fiber sensor has the characteristics of sensitivity, precision and strong adaptability and is widely used in various fields. [0003] In medicine, the Doppler optical fiber velocity sensor is used to measure the blood flow velocity of the subcutaneous tissue. The optical fiber sensor uses the end reflection phenomenon of the optical fiber. The measurement system is simple in structure and can accurately obtain the The concentration and movement rate of red blood cells can then determine the health status of the human body. However, when measuring, the probe is generally placed on the skin to be tested, but it is easy to change the measurem...
